INVALID-BED ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 547,607, dated October8, 1895.

Application filed April 10, 1895. Serial No. 645,162. (No model.)

T0 a/ZZ whom itmay concern.-

Be it known that I, GEORGE H. GOVE, a citizen of the United States,residing at Medina, in the county of Medina and State of Ohio, haveinvented certain new and useful Improvements in Invalid-Bed Attachments,of which the following is a full, clear, and exact description.

My invention relates to that class of invalid-beds having a tilting restfor the purpose of elevating the head or feet, or both, of a sickperson; and it consists of a crank-shaft carrying gears andbox-bearings, a connecting-rod at the base of said rest, screw-threadedshafts engaging threaded holes in said rod at their forward ends andprovided with gears meshing with said crank-shaft gears at theiropposite ends, and yfinger-braces to assist in supporting said threadedshafts, as hereinafter more fully set forth and claimed.

The object of my improvement is to provide an inexpensive, strong, andeasily-operated attachment for use on beds of the class designated,manipulating with an even steady movement, without jar or jolt, andcapable of being quickly and readily attached to or detached from a bedor stretcher. My appliance may be attached to either end of a bed, ortwo appliances may be used, one at each end.

That my invention may be seen and fully understood by others, referencewill be had to the following specification and annexed drawings, forminga part thereof, in which-n Figure 1 is a side View of my invention, therest being depressed; Fig. 2, a side view, the rest being elevated; Fig.3, a top view, the rest elevated; Fig. 4, a longitudinal section, restelevated; Fig. 5, a cross-section on lines m, Fig. 3, looking in thedirection indicated by the arrow d; and Fig. 6 a cross-section on linesyy, Fig. 3, looking in the direction of the arrow Z9.

Similar letters and figures of reference designate like parts in thedrawings and specifi cation. i

The bed or stretcher frame A rests upon the legs 1 and is provided withthe wire mattress 2, held in place by the cleats 3 3. The restB consistsof the arms4 4, the rod 5, connecting said arms at the top, and the wiremattress 6, secured tothe upper edges of said arms. The

arms 4 are pivotally connected to the sides 7 7 of the bed A, on theinside thereof, by the screws or pins 3 8. The lugs 9 9 are secured tothe bases of the arms 4 and are perforated. The bearings 10 10 areattached-to the under edges of the sides 7, near one end, and carry theshaft 11, which is provided on one or both ends with the cranks 12. Thebeveled gears 13 13 are fast on the shaft 11, and the boxbearings C Care loose on said shaft. Each box-bearing C consists of the end pieces14 14,perforated to receive the shaft 11, and the side 15, alsoperforated. The shafts 16 16 are threaded at their forward terminals andhave the beveled gears 17 17 secured to their heads. The gears 17 meshwith the gears 13 in the interior of the bearings C, and the shafts 16pass through the perforations in the sidesl. One of the end pieces 14 ofeach bearing C bears against the gear 13. Hence said bearing is notpermitted to move laterally on the shaft 11,V because said gear is fastto said shaft, and the meshing gear 17 is fast to the head of the shaft16, which bears in the side 15; but said bearing may turn upon shaft 11.The finger-braces 18 18, having the perforated bent terminals 18a 18,are riveted to the sides 15 of the bearings C, and the shafts 16 passthrough the perforations in said terminals. The braces 18 assist insupport-ing the shafts 16 and serve to keep the gears 17 in perfect meshwith the gears 13.

The connecting-rod D consists of the sections 19 19 and the coupling 20.The rod D extends between the rest-lugs 9 and is pivotally attachedthereto. Threaded holes are provided in the sections 19 to receive thethreaded terminals of the shafts 16. The rod D may be made in one piece,omitting the coupling 20, and detachably connected to the lugs 9, ifdesired.

The operation of my device is as follows: To elevate the rest B, turnthe shaft 11 and the gears 13 to the left by means of one or both cranks12, and the gears 17 revolve with the shafts 1,6 in the directionnecessary to reciprocate the rod D toward said shaft 11 by screwing thethreaded terminals of said shafts 16 into and through the rod-sections19. As the shafts 16 turn in the perforated sections 19 and draw themtoward the shaft 11, said sections turn upon their pivotal connectionsICO with the lugst) and draw them downward, causing the arms f1 torotate on the pins S and raise the upper part of the rest B, While atthe same time the box-bearings C turn downward on said shaft 11 with thegears 17 and said shafts 16. After elevating the rest B to the desiredangle cease turning the cranks 12, and said rest is held immovablethrough' the frietional contact of the bearing parts, as will be readilyunderstood. To depress the rest B, revolve the shaft 11 to the right,and a reverse motion is thereby imparted to the several movable parts.

The gears 17 are smaller than the gears 13 in order to impart greaterspeed to the shafts 16 and accelerate the movement of the rest, also toincrease the holding power of said gears.

Both gears 13 may be brought close to the sides 7 with teeth adjacent toeach other, if desired, and right and left hand threads eut on theshafts 16 and in the perforated rodseetions 19, respectively; but thearrangement shown and described is deemed to be the best.

To remove my device from the frame A it is only necessary to unfastenthe bearings 10, uncouple the rod-sections 19, take out the pins i 8,and separate the shafts 16 from said seci tions. i

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination in a bed attachment, of

a rest pivotally attached to the sides of the bed and provided with lugsat the bases of its arms, a rod pivotally connecting said lugs andhaving threaded perforations thereon, a crank shaft j ournaled to saidsides, gears fast on said shaft and perforated box-bearings loosethereon, perforated nger-braces secured to said bearings, shaftsextending through the perforations in said bearings and braces havingthreaded terminals for engagement with said perforated rod, and gearsfast on the heads of said threaded shafts meshing with the gears on saidcrank shaft Within said box'bearings, substantially as and for thepurpose set forth.

2. In combination with a bed having a tilting rest, a crank shaftjournaled to the sides of the bed, gears fast on said shaft andperforated box-bearings loose thereon, shafts eX- tending through theperforations in said bearings having threaded terminals for engagementwith a perforated rod pivotally connecting the arms of said rest, andgears fast on the heads of said threaded shafts meshing with the gearson said crank shaft within said box-bearings, substantially as and forthe purpose set forth.

In testimony whereof l ailix my signature in presence of two Witnesses.

GEORGE Il. GOVE.
